This could drag on, but I really don't think I could ever put "then"
in there. "Until then" seems to me to use "then" to refer to a time
already known to the reader. "Then after" would go in something like
"He got to the top; then, after seeing tracks, he walked over..."
"Until after" would work in "The car coasted until after he saw the
tracks..." I can't do much here with "until then after". A quibble, I
dare say, but this is a.u.e.
